Design Flow w/ Im perme able Fence represents

conservative condition w/ no flow through fence.

Design Flow w/ Fence represented as post in

floodplain allow ing free flow through fence. The actual

hydraulic impact will lie between these two situations.

Conclusion:

All criteria met on Mexico side. On U S side, exceeds deflection criteria by 0.73% andwater surface elevation criteria by 3.84". Floodplain expan ds by on ly 24' and

velocity increase s by 0.12 fps. The imp act is limited to agricultural land, natural area

open space, and a few s tructures, all of which are located in the existing flood plain.

No n ew structures added; therefore, no impact to US .
